Fecal coliforms

coli, in a water source is an indication of the presence human or animal waste matter in the water. These bacteria are a type of fecal coliform bacteria found in the intestines of humans and animals. Drinking water that contains E. coli bacteria may cause diarrhea, abdominal cramps, headaches and nausea. Young children and elderly people may be more susceptible to the adverse effects…

The Chesapeake Bay’s water quality has been deteriorating over the recent years. Some reasons for the decrease in quality are agriculture, chemical contaminates, and sediment. Agriculture has caused problems for the Bay due to the use of fertilizer. When it rains, the excess nutrients run off into the waterways that lead to the Bay. These excess nutrients include nitrogen and phosphorus. When these nutrients get into the Bay, it causes an algae bloom. The algae bloom blocks any light from…

With the rate at which our planets population is growing, what are we going to eat when we run out of room to plant crops, raise animals? There is always the option of genetically modified organisms or GMO’s, meats that are grown in labratories, algae, or even insects, but all of these are “temporary fixes” to the real problem. How can we sustainably survive on this planet at all if we continue down this path of over consumption? According to the Non GMO Project, GMO’s are defined as living…

of many harmful bacteria in water, therefore, the testing for the presence of E. coli in different water samples was performed. In this project, water samples gathered from water fountains around the school and two water bottle brands were tested. Coliform cult tests were performed, testing for E. coli in the water. Also, water test strips were used to test for total alkalinity, free chlorine, pH, total hardness (amount of calcium carbonate), total chlorine, cyanuric acid, nitrate, nitrite, and…

Did you know that about 20% of the world claim to be vegans? People who are vegans claim to be helping themselves and the world around them but they really aren’t. In fact they seem to be doing more harm to themselves and the world around them. Veganism is not as good for the world as it seems because people don’t get all the nutrients you need in a meal, it's bad for the environment, and it’s also bad for the animals. People who are vegans lack all the nutrients they need to get in a full…

To determine the overall water quality difference between the canal and the Great falls, we have to first understand the differences between each water quality parameter and what it means.By starting with our first test, PH, we can see that the canal has a higher PH level, thus being more basic than the Great falls. However, both are in the 7.1-9.5 range, and can be classified under the low alkalinity condition which is described as “High-quality water with good productivity,” allowing “Lakes…

2.1 Introduction In this career episode, I shall describe major project performed during course of my employment in Pakistan Council of Research in Water Resource “RCRWR” which functions under Ministry of Science and Technology, Federal Government of Pakistan. I was appointed as Assistant Director and I am going to describe the project KHUSHAL PAKISTAN PROGRAMME (Devolution Support Program) for the provision of safe drinking water. This career episode took place from March till October 2007…

Every day consumers make the decision to either purchase a water bottle or drink water from the faucet. Consumers base their decisions on taste, ads, or labels, even though the labels are just for hype. For example, Margolin said if the fine print was looked at carefully, consumers would see that Everest Water does not come from Mount Everest; their water comes from Corpus Christi, Texas. Also, another brand of bottled water, Glacier Clear Water does not come from a glacier in Alaska like it may…

(MSA) to inhibit the growth of most organisms and differentiate possible pathogenic staphylococci, Phenylethyl alcohol (PEA) agar to grow gram-positive organisms, Eosin methylene blue (EMB) agar to cultivate gram-negative bacteria and isolate fecal coliforms, and Nutrient agar for a general purpose to support the growth of the unknowns. All plates were incubated at 35˚C for 24 to 48 hours. Bacterial growth, colony-descriptions, colonies and plates color and color changes were observed,…

Escherichia Coli, or E. Coli, are a large and diverse colony of bacteria within the fecal coliforms group – a group of closely related bacterial genera that share the ability to metabolize sugar lactose, producing acids and gas as byproducts – found living harmlessly in warm-blooded organisms’ intestines, the environment, or in various foods (2006). Unfortunately, some forms of E. Coli bacteria are pathogenic, in which the bacteria has developed the ability to cause the disease of the urinary,…
